Definitions
- This invention relates to flavors and specifically to modified pineapple ketone.
- Pineapple ketone is the common name for the chemical 2,5-dimethyl-4-hydroxy-3(2H)-furanone. This is a compound found in pineapples, strawberries, raspberries, meats, and other foods. It has been found in cooked, roasted and fermented foods including coffee, roasted filbert, roasted almond and soy sauce. Pineapple ketone is known to be formed by the non-enzymatic browning process that occurs during roasting and baking.
- pineapple ketone Because of its cotton-candy, carmelized-sugar flavor, pineapple ketone is used extensively to compound synthetic flavors. Pineapple ketone reacts readily with amines, aldehydes and oxygen. In such cases, the pineapple ketone content of the flavors is reduced, lowering the effectiveness of the flavor.
- pineapple ketone When pineapple ketone is used in chewing-gum, it is quickly “washed out” by the chewing process, resulting in rapid loss of flavor. This "washing out” effect is due to pineapple ketone being water soluble.
- a new pineapple ketone carbonate compound having the general formula, wherein R 1 and R 2 independently are -H,-CH 3 , or -CH 2 CH 3 ; -and R 3 is alkyl of from 1 to 10 carbons or aryl of from 6 to 10 carbons.
- the invention solves the wash out problems associated with the use of pineapple ketone, while extending the flavor over a longer period of time.
- pineapple ketone By reacting pineapple ketone with an ethyl chloroformate or other alkyl chloroformates in triethylamine, the new and improved pineapple ketone carbonates are formed.
- the invention relates to new carbonates derived from pineapple ketone.
- the chemical reactivity of the resulting compounds is unexpectedly reduced compared with pineapple ketone; however, the flavor of the derivatives remains very similar to the flavor of pineapple ketone.
- This allows direct replacement of new carbonate derivatives in applications where pineapple ketone is normally used.
- the increased oxidative stability of these derivatives over pineapple ketone allow their use in applications where pineapple ketone cannot be used or does not perform well.
- Such applications include but are not limited to perfumes, dry flavors and tobacco.
- the new carbonate derivatives are not as water soluble as pineapple ketone, which allows these derivatives to be preferentially dissolved by chewing- or bubble-gum-base. This effect allows the derivatives to liberate pineapple ketone-like flavor slowly during the duration of the chew, creating a flavor prolongation effect.
- the method of making new carbonates are novel because, although alcohols are known to react with ethyl chloroformate and other alkyl chloroformates to form alkyl carbonate derivatives, ketones or diones are not known to react with alkyl chloroformates to form carbonate derivatives.
- An unexpected aspect of the invention is that the subject derivatives are more stable to oxidation than pineapple ketone.
- Hirvi, et al. [Lebensm.-Wiss. u.-Technol., 13, 324 (1980)] have indicated how sensitive pineapple ketone is to oxidation. At pH 4 it has a half-life of 120 days, while at pH 7 it has a half-life of 12 days.
- the increased oxidative stability of the subject carbonate derivatives over pineapple ketone is given in Example 3.
- An unexpected aspect of this invention is that the derivatives have a similar taste to pineapple ketone.
- Exemplary of the preferred extended flavor compounds and the invention are:
- a typical bubble gum base is made with the following ingredients: All ingredients are mixed in a gum blender with a jacketed sidewall. To gum A is added 7.50 parts strawberry flavor 500389-U (Hercules, PFW Division, Middletown, NY). To gum B is added 7.125 parts strawberry flavor 500389-U, plus 0.375 parts of ethyl carbonate pineapple ketone derivative from Example 1. The gums are cut into 5.0 grams pieces and evaluated by panelists. Both gums A and B have a long-lived strawberry flavor, with gum B having a higher overall rating for flavor prolongation after 10 minutes, as well as, having a higher and more sustained flavor intensity peak during the middle of the chew. Gum B has the best retained strawberry character throughout the chew.
